Recently, in producing manufacturer by domestic rail build exclusively rail solders the Pan Gang steel of the lab grinds the aluminium of rail of Pan Gang U75V that courtyard material institute and company of new steel vanadium begin heats up solder technology to study a task, save appraisal of hall of science and technology through Sichuan recently. Come for years, pan Gang solders by right of its rail the advantage of lab equipment and technology, began flashy solder, baric solder and aluminous hot solder early or late 3 kinds solder methodological science and technology tackles key problem, applied these positive result in railroad branch promotion. Climb PD3 of small vanadium of steel tall carbon for the evaluation (show a name " U75V " ) the weldability that rail heats up solder craft condition to fall in aluminium can, involve the market share of steel rail with expanding further, promote aluminium of our country rail standard of hot solder technology, task group is aimed at how to control welder art parameter and how to eliminate the technical difficulty such as contact weld defects to undertake study, the lot that has burden characteristic in coal chemical plant took site of coal machine track to undertake course of study experiments do not have suture road welder. Test result makes clear, rail of Pan Gang U75V solders the technical requirement that contact quality can reach level of TB ／ T1632 in the round, endure so that a high speed, heavy-load train solders to rail contact is violent percussive is austere test. The expert thinks, this research achievement already reached domestic banner level, after railway system popularizes application social benefit is mixed economic benefits is very remarkable.
